Maine rules that apply to Versant Power

The state framework sets the default. Where Versant Power pays something different, the utility tariff governs and is what the card above reports.

Compensation mechanismMaine has two NEB variants: a kWh Credit Program that credits participating bills in kilowatt-hours, and a Tariff Rate Program for non-residential customers that provides dollar bill credits based on the PUC-set tariff rate and facility output.
Export rateThere is no single statewide export price. The kWh Credit Program provides kWh credits rather than a fixed dollar rate; the Tariff Rate Program uses annually established, project- and customer-specific tariff rates published by the PUC.
Rate effectiveTariff rates are established for 12-month periods beginning January 1 and ending December 31; the PUC page states its current rate schedule was established on December 17, 2025 for periods through 2046.
Credit rolloverYes. Unused kWh or dollar credits may be accumulated and applied on a rolling 12-month basis.
Credit expirationUnused kWh or dollar credits are eliminated at the end of the applicable 12-month period, with no compensation for the unused credits.
Annual true-upNo separate annual true-up date is specified in the reviewed sources; credits are handled on a rolling 12-month basis and expire at the end of that period.
Aggregate program capNo statewide aggregate percentage cap is stated in the cited statutes or MPUC NEB page. Section 3209-A states a 750 MW development goal; that is a goal, not described as an aggregate program cap.
Program statusThe 2025 law bars the Commission after December 31, 2025 from allowing new NEB agreements for resources interconnected or planned on the utility side of a customer meter; existing agreements and behind-the-meter arrangements are governed by the applicable statutes and rules.
GrandfatheringYes, in limited statutory/program respects: the commercial and institutional collocation/100%-subscription limitation does not apply to a NEB agreement executed on or before December 31, 2023, and statutory applicability provisions preserve the significance of earlier agreements and milestones.
RegulatorMaine Public Utilities Commission (MPUC). The CMP and Versant tariff agreements identify the Commission as the state regulatory agency with jurisdiction over public utilities.
Governing rule35-A M.R.S. §§ 3209-A and 3209-B, implemented through the Maine Public Utilities Commission Chapter 313 Net Energy Billing rule.
Pending changeNo separate pending change was identified in the reviewed sources as of September 16, 2026. The material 2025 changes are enacted law: after December 31, 2025, new utility-side-of-meter NEB agreements are barred under §§ 3209-A(10)-(11) and 3209-B(9).
